MACROMOLECULES THE STUFF OF LIFE
LATIN 101 • Poly – Many • Mono-One • Hydro-Water (actually Greek) • Synthesis- to make or form • Lysis-loosen; break apart • Lipos - fat
Carbon compounds and cells • Life as we know it is carbon based. • A carbon atom can form chemical bonds with other carbon atoms in long chains or rings.
Carbon compounds and cells • Carbon compounds in living things include: carbohydrates, proteins, lipids and nucleic acids.
Polymers – large organic molecules made of smaller parts known as monomers (Building blocks of polymers)
Dehydration synthesis • The chemical process of joining monomers to form polymers. At the end of each monomer is a (H) hydrogen atom and a (-OH) group. Every time a monomer is added a molecule of water is given off.
HYDROLYSIS • The chemical breakdown of polymers into monomers through the addition of water; essentially the opposite of dehydration synthesis
Carbohydrates • Carbohydrates are energy-rich compounds made from carbon, hydrogen, and oxygen. • Cells use carbohydrates to get and store energy. • Carbohydrates are also called sugars or starches. Structure- ring-shaped molecule
carbohydrate Dehydration Synthesis Hydrolysis
Lipids • Lipids are made by cells to store energy for long periods of time. • Lipids include fats, oils, and waxes. Can you think of examples of lipids in plants or animals?
LIPIDS-1 Glycerol and fatty acid tails- Structure 3 FATTY ACID TAILS GLYCEROL BACKBONE
LIPID Dehydration Synthesis Hydrolysis
Proteins • Proteins are very large molecules made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. • Protein molecules are made of smaller molecules called amino acids.
PROTEINS Dehydration Synthesis Hydrolysis
R-Group (Makes each Amino Acid Different ; 20 different amino ACIDS) - Contain Nitrogen
Nucleic acids • Nucleic acids are compounds made of long, repeating chains called nucleotides. • DNA is a nucleic acid that contains the information cells need to make all of their proteins.
DNA • Some scientists refer to DNA as the “blueprints” for life. What is a blueprint and why might scientists use this “analogy”?

MACROMOLECULE FOLDABLE Fold and cut a piece of paper as shown below to make 4 tabs. FolDABLE TIME • FRONT SIDE OF TABS: • Tab A • Label the tab PROTEIN in RED • Write the name of its monomer and draw and color one. • TAB B • Label the tab CARBOHYDRATE in BLUE • Write the name of its monomer and draw and color one • TAB C • Label the tab LIPID in GREEN • Write the name of its monomer and draw and color one • TAB D • Label the tab NUCLEIC ACID – a color not already used • Write the name of its monomer and draw and color one • BACK SIDE OF TABS: • TAB A • Give 4 FUNCTIONS OF PROTEINS • List 2 EXAMPLES OF PROTEINS • TAB B • Give 2 FUNCTIONS OF CARBOHYDRATES • List 4 EXAMPLES OF CARBOHYDRATES • TAB C • Give 3 FUNCTIONS OF LIPIDS • List 4 EXAMPLES OF LIPIDS • TAB D • Give 2 FUNCTIONS FOR NUCLEIC ACIDS • List 2 EXAMPLES OF NUCLEIC ACIDS • ON THE INSIDE CENTER SECTION, center and write the word MACROMOLECULE • ON THE BACK OF THE FOLDABLE, write your NAME and PERIOD. • Make a pocket for this to slide into in your notebook using paper.
ORGANIC-COMPOUNDS THAT CONTAIN THE ELEMENT CARBON 95% of all compounds are organic Example: Glucose C6H12O6
Carbohydrates • Plant cells store energy as starch. • Rice, potatoes, and wheat are plant starches.
